You will need to add the wires for VTEC and the knock sensor, but you do not need a mount kit. The B16 cable tranny will work fine. Are you sure this is the swap you want? The B16 is great in a Civic, but kinda torqueless for a heavier car like the Integra. I know the DA came with a B16 for 3 years, blah blah blah. There is a reason it only lasted 3 years and the B18C(1) lasted 7...

Just make sure you know what you are getting before you buy. Good luck.
